The Silicone Bifins 2 are the next generation of our best-selling training bifins, built with feedback from thousands of freedivers worldwide. The blade geometry has been updated for a firmer, more powerful kick, while a new adjustable heel strap means the fit works for more feet—with or without neoprene socks. Hypoallergenic silicone, an anatomical open-heel foot pocket with arch support, and a blade design inspired by our competition fins make these the most versatile silicone training fins on the market, whether you’re a beginner building technique or an advanced freediver refining it.
Please note:
Bright colors may fade over time when exposed to sunlight. To minimize fading, rinse and store fins away from direct UV light when not in use.
Firmer, more powerful blade
Updated blade geometry delivers a more stable, efficient kick than the previous generation. This results in better propulsion for both pool training and open water, while remaining soft enough for technique-focused training at every level.
Stabilizing blade rails
Eight blade rails with a specific curvature profile distribute stiffness across the blade for maximum efficiency with minimum effort, inspired by the geometry of our PRO Line carbon bifins.
Anatomical foot pocket
Dedicated right and left foot pockets with arch support keep your foot in the optimal pointed-toe position while finning, maintaining efficiency and preparing you for a seamless transition into performance bifins. The soft silicone construction means the foot pockets won't dig in or irritate, so you can focus on technique rather than your feet.
Open-heel design
An open-heel foot pocket gives you the correct ankle-to-foot position while finning, along with a full range of motion through each kick.
Adjustable heel strap
A new adjustable heel strap lets you customize the fit for your foot, whether you prefer a snug fit, dive with neoprene socks, or need extra room for comfort.
Hypoallergenic silicone
UV-resistant, hypoallergenic silicone performs at any water temperature and won't degrade in the pool or the sea. A new, more durable and flexible formula allows for a thinner blade than the first generation silicone bifins.
